sense in the lessons
In science and geography humidity is part of weather and climate: it is measured with a hygrometer and is often given as «relative humidity» in percent — how full of water vapour the air is compared with the most it can hold at that temperature. High humidity makes hot days feel hotter because sweat dries slowly. Weather forecasts give humidity, and it matters for plants, rainforests, deserts and bathrooms. Phrases: high humidity, low humidity, relative humidity, humidity level.

note
Uncountable: «the humidity is high», not «humidities» in everyday use. Adjective: «humid» (a humid day). In maths and science, relative humidity is a percentage from 0% (completely dry) to 100% (air holds all the water vapour it can; dew or fog may form). It is not the same as rainfall: air can be humid without rain. Opposite feeling: dry air.
